TBAC 30P-1, fully welded, so I will have to dip it when I decide to clean it.
I've only run about 50 .22lr rounds through it because I don't want to have to dip it for a while. The adapter allow me to run the can on my 5.56 uppers, which I haven't had a chance to try yet. I need to get a better brass catcher, so I can harvest my 5.56 brass to cut down for .300blk.
That's where this can is really awesome, subsonic 300blk is spooky quiet.
